Overview ▾

The pkgfact package is a demonstration and test of the package fact mechanism.

The output of the pkgfact analysis is a set of key/values pairs gathered from the analyzed package and its imported dependencies. Each key/value pair comes from a top-level constant declaration whose name starts and ends with "_". For example: 

package p

const _greeting_  = "hello"
const _audience_  = "world"

the pkgfact analysis output for package p would be: 

{"greeting": "hello", "audience": "world"}.

In addition, the analysis reports a diagnostic at each import showing which key/value pairs it contributes.
